Cylindrical & Planetary Rolling Dies China Sourcing | SourcingProChina Cylindrical & Planetary Rolling Dies – Up to 380mm OD | Sourced from China
Product Overview SourcingProChina, a China-based sourcing agent, connects overseas buyers with vetted manufacturers of cylindrical and planetary rolling dies for thread rolling, knurling, burnishing, and profile-forming applications. We coordinate sourcing, quality verification, and order fulfillment on your behalf, giving you access to precision tooling without the risk of managing factories directly.
Cylindrical Rolling Dies Cylindrical rolling dies are designed for all types of cylindrical thread rolling machines. Dies sourced through our network support both in-feed and through-feed thread rolling operations, as well as specialty applications including knurling, burnishing, and screw straightening.
Technical Specifications Parameter Specification Maximum Outer Diameter 380mm Thread Rolling Methods In-feed and through-feed Special Features Annular ring dies for corrected pitch and combined helix Additional Capabilities Straight knurls, diamond knurls, profile burnishing, screw straightening
Key Applications In-feed thread rolling (parallel thread rolling) Through-feed thread rolling (continuous thread rolling) Straight and diamond knurl production Profile burnishing and surface finishing Screw straightening operations Corrected pitch and combined helix rolling Planetary Rolling Dies Planetary rolling dies are specifically designed for the production of pointed screws and special thread profiles. These dies are suited to high-volume manufacturing of self-tapping screws, wood screws, and specialty fasteners with custom thread geometries.
Key Features Pointed screw capability – optimized for pointed and self-tapping screw production Special profile support – capable of producing custom thread profiles and complex geometries High-volume production – engineered for continuous mass-manufacturing cycles Dimensional consistency – tolerance class [Data Required] maintained per production batch Key Applications Pointed screw manufacturing Self-tapping screw production Wood screw thread rolling Special thread profile forming High-volume fastener production Common Features & Advantages Material selection matched to application (see Material & Grade Selection table below), rather than a single generic grade Manufacturing tolerances verified per batch: tolerance grade [Data Required] Profile range covers standard threads, straight/diamond knurls, and custom geometries as specified by the buyer's drawing Custom configurations available in dimension, profile, and material, coordinated with partner factories per buyer specification Sourcing and technical support provided by SourcingProChina throughout die selection, factory vetting, and order follow-up Material & Grade Selection Application Recommended Material Key Properties Standard thread rolling High-speed steel (M2) Good wear resistance, cost-effective High-volume production Powder metallurgy steel (ASP30/ASP60) Superior wear resistance, extended life Hard material rolling Tungsten carbide / specialty grades Maximum wear resistance, high hardness

Frequently Asked Questions Q1: What is the difference between cylindrical and planetary rolling dies? Cylindrical rolling dies are used for general thread rolling on cylindrical thread rolling machines, suitable for most bolt and screw applications. Planetary rolling dies are designed for pointed screw and special profile applications, ideal for self-tapping and wood screws.
Q2: What is the maximum outer diameter for cylindrical rolling dies? Cylindrical rolling dies sourced through SourcingProChina are available up to 380mm outer diameter.
Q3: What types of thread rolling do cylindrical dies support? Both in-feed (for parallel threads) and through-feed (for continuous threads) rolling methods are supported.
Q4: Can these dies produce knurls? Yes, both straight and diamond knurls can be produced using cylindrical rolling dies sourced through our network.
Q5: Do you offer custom profile rolling dies? Yes. As a sourcing agent, SourcingProChina coordinates with partner factories to manufacture custom cylindrical and planetary rolling dies for special thread profiles and geometries based on buyer specifications.
Q6: What materials are used for these rolling dies? Materials include M2 high-speed steel, ASP30/ASP60 powder metallurgy steel, and tungsten carbide, selected according to application requirements as outlined in the Material & Grade Selection table.
Q7: What products are planetary rolling dies typically used for? Planetary rolling dies are primarily used for pointed screws, self-tapping screws, wood screws, and specialty fasteners with custom thread profiles.
Q8: Do you offer support for die selection? Yes. SourcingProChina's sourcing team assists with material selection and die specification, and coordinates directly with manufacturing partners on the buyer's behalf.
